I did it for the first time last year. Great, fast track. Tips: the track surface around the chicanes is / was a bit shite, unless it's been fixed since. When I was there it rained and someone put oil all round the track on the racing line very early on. I saw it and came in to the pits (along with a few others) after nearly losing it on turn 2. The session continued for some time and it was only after 4 riders had crashed out did the marshals wake up and close the circuit for a hour to clean up the oil. Duh?
